Moderator Airhead Posted April 29, 2012 Moderator Posted April 29, 2012 just measure yours up and give them a ring before you order the nipple
thomasrolewis Posted April 29, 2012 Author Posted April 29, 2012 Because it's snapped off I have no idea. The size of the hole is 5mm so I presume that's it. I emailed them earlier, but I'll ring them tomorrow to make sure.
Moderator Airhead Posted April 29, 2012 Moderator Posted April 29, 2012 have you managed to get the snapped nipple out of the caliper then?
thomasrolewis Posted April 29, 2012 Author Posted April 29, 2012 The bolt just snapped, the nipple was really badly corroded and as I turned it snapped. This whole calliper is a mess but hopefully it will be ok after fixing it. That's if I can get the nipple out.
Moderator Airhead Posted April 29, 2012 Moderator Posted April 29, 2012 yep you'll need easy out's and heat as DirtyDT posted
thomasrolewis Posted April 29, 2012 Author Posted April 29, 2012 I bought a set of the screw things, i'll use a soldering iron to heat up the screw. We'll see how it goes.
Moderator Airhead Posted April 29, 2012 Moderator Posted April 29, 2012 you'll need a blowtotch, a soldering iron wont touch it. Failing a blowtorch maybe boil it in a pan? then spray a little penetrating oil on the screw...(take precautions, dont burn your hands!)
thomasrolewis Posted April 29, 2012 Author Posted April 29, 2012 Don't I only want to heat the screw? If not boiling it will be fine I think. I don't have a blowtorch unfortunately.
Moderator Airhead Posted April 29, 2012 Moderator Posted April 29, 2012 no you need to heat the caliper so it will expand fractionally, then spray inside the screw to cool the screw and so contract that item...work quickly
slice Posted April 30, 2012 Posted April 30, 2012 No blowtorch then use your oven, gas mark 6 (15mins) and cool the broken nipple thread with and ice cube.
KirriePete Posted April 30, 2012 Posted April 30, 2012 Better yet, just leave the snapped nipple in place as drilling it out may well end up with you buggering the seat if you go too far with the drill. Then go get a banjo bolt with built-in bleed nipple - 10mm x 1.25mm bleed banjo from WEMoto - just remember to tilt the caliper so that the banjo is at the highest point when you bleed it.
thomasrolewis Posted May 1, 2012 Author Posted May 1, 2012 I will try and get the pin out using a set of bolt extractors + heat (new nipple and extractors arrived today, worth a shot?). If It looks like it wont come out I will buy one of them banjo bolts! I wish I had done that first!
thomasrolewis Posted May 1, 2012 Author Posted May 1, 2012 In fact, I won't even risk it. I'll test to make sure it's sealed and then buy a banjo nipple combo bolt! Also Airhead, those seals were perfect! Thanks.
Moderator DirtyDT Posted May 1, 2012 Moderator Posted May 1, 2012 Personally I would drill it out. The heat of drilling it and some plus gas may loosen it up enough to get the bolt extractor on it.
thomasrolewis Posted May 1, 2012 Author Posted May 1, 2012 Personally I would drill it out. The heat of drilling it and some plus gas may loosen it up enough to get the bolt extractor on it. I know what you mean, it would be nice to get it out. But I really don't want to break it - as I would have to buy a new calliper.
thomasrolewis Posted May 3, 2012 Author Posted May 3, 2012 OK, I put it all together today. I think it works, although I just got off and I felt some moisture on the bottom of the calliper. Please say my piston seals are not leaking, please. I will check again tomorrow, I have a spare pair of seals so I might be ok.
thomasrolewis Posted May 4, 2012 Author Posted May 4, 2012 Scratch that, it's f**ked. It's leaking past the seals, both sets. I guess its either a whole new calliper or take it into a garage.
thomasrolewis Posted May 4, 2012 Author Posted May 4, 2012 I know, I know. The thing I don't understand is why it's leaking though. I totally wasted a lot of money, and now I can't find a spare one.
